Reality
A popular claim in wellness circles, seed oils are not toxic or inflammatory.
Polyunsaturated Fatty Acids (PUFAs) consist of two fatty acid groups: Omega 3 & Omega 6. Both are essential and can only be ingested via food or supplementation.
Linoleic acid (LA) plays a big role in Omega-6 fats. Seed oils are a good source for this fat. LA can:
support reduced LDL cholesterol and inflammation in the body
decreased risks of cardiovascular disease (CVD), diabetes, and premature death
Arachidonic Acid (ARA) is also found in Omega-6 fats and is health protective. This fat:
plays important roles during hormone production
may benefit muscle and cognitive performance
may increase or decrease inflammation
The three main acids in Omega-3 fats are alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). These acids:
play protective roles that can reduce risks of developing metabolic and inflammatory diseases
safeguard against the development of chronic diseases, especially when underpinned by excessive inflammation
Seed oils aren’t bad, unhealthy, toxic or inflammatory; they’re health supportive & associated with reduced inflammation + reduced chronic disease risks. Swapping saturated fats (e.g. butter) for PUFAs (e.g. canola oil) is recommended for good health, especially heart health.
